"My perfect efi folder is backed up on a USB drive"

Yesterday I installed fresh Catalina os on my drive and everything went smooth up until I restarted the PC, right after that can't boot into any of my 3 drives and not even from the USB stick. My bios untouched.

I loaded the default settings of the bios and configured it again and again just to make sure I haven't missed anything. Updated the bios to 2002 and still nothing changed.

While waiting for suggestions, I will un-plug the ssd's and check if it get to work.

Folks I appreciate any suggestions here. It's only a matter of time until apple releases the mac pro and I will definitely buy it.
